STEPHEN J. KU'IBEL, or WASHINGTON, msrnrc'r or COLUMBIA:

Be it known that I, STEPHEN J. KI'iBEL, a citizen of the United States,residing at Washington, in the District of .Columb1a, have invented newand useful Improvements in Visual Signals, of which the following is aspecification.

Pilots of steamboats and boats of other classes are rarely enabled tohear clearly or at all the course-signals given by the comthan steamblasts), the horns or other audible signals with which 7 motor boats andother boats are equipped, and this failure to distinguish signals is aserious menace to navigation. It is also well known to operators ofmotor boats propelled by internal combustion engines that the-pilot ofsuch a boat, because of the noise made by the pro pelling machinerytherein, is frequently unable to hear the whistle, horn or other audibledevice and ascertain the course-signal of an approaching boat, and hencethe handling of such boats is always attended by more or less danger.

One of the objects of my present invention is to provide a visual signalintended primarily for use in the daylight .and through the medium ofwhich the pilot of a boat not equipped with a steam whistle can acquaintthose in. another vessel of the course he proposes to take. While myv1sual signal is intended primarily for use in the daytime, I would haveit distinctly understood that when illuminating means of any suitablekind is employed, the signal may be-made visible at night.

Another object of the invention is the provision of an audible signaland a visual signal; the said audible and visual signals being socombined as to be operated synchronously.

Another object is the provision for signal purposes of two chemicals orgases adapted when combined to form smoke or vapor, and means forbringing about the commingling and emission of the said chemicalsorgases in theform of smoke or vapor plainly visible in the atmosphere.The chemicals I prefer to employ are ammonia and hydrochloric acid, andwhen these are combined ammonium chlorid is formed; ammonium embodimentof yet revised.

other when combined, and the vapor given I tion with the drawing,accompanying and A forming part of this specification, in which:

hefi'gure 1s a view, partly in elevation and partly in sectlon, of thebest practical my invention that I have as In theillustrated andpreferred embodiment of my invention, I employ a Whistle A which per semaybe of'any type consonant with the purpose of my invention withoutinvolving departure from the scope of same as claimed. The said whistleis connected through a suitable conduit B with a reservoir (3, chargedin any approved manner with air or other suitable fluid under pressure,and in the conduit'B at a suitable point is located a conventional orother approved valve D, the opening of which will bring about thepassage of fluid under pressure to the whistle and the sounding of thelatter.

Located by preference at one side of and in close proximity to thewhistle A is an ejecting tube E, disposed vertically, and connected withthe lower end of the said tube is a conduit F through which the fluidunder pressure and the smoke or vaporforming means are permitted to passas hereinafter set forth.

posite side of the valve D, with reference to the source offluid-pressure supply C, is aconduit G through which a portion of eachblast of fluid under pressure is permitted to pass when the valve D isopened to sound the whistle A The said conduit G has for its ofiice toconduct a portion of the fluid under pressure to the chemical containingvessel, with a view to displacing and commingling the chemicals andejecting the same in the form of smoke or vapor through the tube E, andthis synchronously with the comprises an outer receptacle or member H,designed to contain hydrochloric acid, an inner receptacle or member Iadapted .to contain ammonia and keep the same isolated from thehydrochloric acid, an individual cover J for the receptacle or member Hto a point adjacent the bottom thereof, and the conduit N extending downinto the receptacle or member I to a point near the bottom of thereceptacle or member. It will also be understood that a conduit Peflects communication between the receptacle I and the conduit F, and aconduit Q effects connect-ion between the interior of the receptacle Hand said conduit F. By

virtue of this it will be manifest that when i the: valve D is opened tosound the whistle A, a portion of the fluid under pressure will passthrough the conduit G and the subconduits M and N into the receptacles Hand I respectively. The hydrochloric acid and ammonia are gasesdissolved in water, and when the fluid under pressure is let a into thereceptacles or containers H and I as stated, such fluid under pressurewill liberate the gases from the water and will pass with the gases tothe conduit F. When the said gases contact with each other in theconduit F ammonium chlorid is formed, as before stated, and this latteris emitted.

with the blast of fluidunder pressure from the tube E, and constitutes avisual si and one that does not dissipate as quickly as'steam orordinary smoke.

the .soundingof the whistle A.

By reason of the emission of the visual signal each time that thewhistle-is sounded, the-pilot of an approaching boat will be apprised ofthe sounding of the whistle evenf if he can not hear the same, and hencewill be-made cognizant of the course-signal given. 2 It will also beunderstood in this connection that the emission of the visual signalfrom? the tube E will correspond in length with; the blasts of thewhistle Ai. 6., long blasts? of the whistle will be attended bycorrespondingly long emissions of the visual sig-; nal, while shortblasts of the whistle will be; accompanied by similar short emissionsof?"the visual-signal or visual-signal means.-

Consequently by observing a boat equipped with my improvements, thepilot of another boat is enabled toclearly understand the course-signalsthat are given on the boat so equipped even if he can not hear thewhistle thereof.

'It is to be distinctly understood that my invention is not restrictedto the specific means shown and described for forming and ejectingblasts of substance clearly visible al 5 that is plainly to be seen inthe atmosphere,

It will also be understood here that the emission of the ammoniumchlorid-will be synchronous with in the atmosphere in concert withblasts of the whistle. On the other hand the emissions visible in theatmosphere may be formed by any suitable means and may be dischargedinto the atmosphere in any approved manner without involving departuremeans,'other than steam, and being discharged into the atmosphere in anyapproved manner, and used in combination with a whistle, a hornor otheraudiblei. 0., noise-ma king, device. I would further have it understoodthat when the illustrated embodiment is employed, including a valve suchas D, or any other valve intermediate the source of fluid-pressuresupply and the whistle and controlling a conduit that extends betweenthe said elements, the said valve may be arranged at any suitable ointbetween the reservoir G and the whist e A, without departure fromthescope of my claimed invention.

-- Having described my invention, what I claim and desire to secure byLetters-Patent, 1s:

1. In a signal means, the combination of an audible signal, a tubearranged adjacent thereto and disposed to discharge upward, a source offluid-pressure supply, containers, a conduit intermediate the containersand said tube, chemicals in said containers, adapted when commingled toform a signalmeans visible in the atmosphere, a conduit intermediate thesource of fluid-pressure supply and the audible signal, a valvecontrolling the passage of fluid-pressure through said conduit, and aconduit leading from the second named conduit, at the opposite side ofthe valve with reference to the source of fluid-pressure supply, to theinteriors of the containers, .whereby opening of the valve will causesounding of'the audible signal and a synchronous emission ofvisualsignal means from the tube.

2. In signal means, the combination of an audible signal, a tubearranged adjacent thereto and disposed to discharge upward, a source offluid-pressure supply, containing means, means in said containing meansadapted when discharged into the atmosphere to constitute a visualsignal, a conduit intermediate said containing means and the tube, aconduit intermediate the source of fluid-pressure supply and the audlblesignal, a valve controlling the passage of fluid-pressure through saidconduit, and a conduit leading from the second named conduit, at theopposite side of the valve with reference to the source offluid-pressure supply, to the interior of the containin means, wherebyopening of the valve w'l cause sounding of the audible signal and asynchronous'emission of the visual-signal means from the tube.

3. In signal means, the combination of an audible signal, avisual-signal discharge tube, containers, a conduit intermediate thecontainers and said tube, chemicals in said containers, adapted whencommingled to form signal means visible in the atmosphere, and means forsynchronously sounding the audible signal and liberating chemicals fromthe containers and emitting the commin'gled chemicals through the tube.

4. The combination of an audible signal, means for supplying the audiblesignal with fluid under pressure to actuate" the same, a containerhaving a discharge orifice separate from the audible signal, means inthe con-.

tainer adapted when discharged through said orifice thereof and into theatmosphere to contrast therewith and constitute a signal visible in theatmosphere during daylight, and means for supplying the container withfluid under pressure synchronously with the supply of fluid underpressure to the audible signal, whereby the soundings of the audiblesignal and the emissions of the visual-signal means will correspond induration as will also the intervals between the soundin s of the audiblesignal and the emissions 0 the visual-signal means.

5. An audible signal, a container having a discharge orifice apart or searate from the audible signal, means in t e container which means is ofsuch character that when discharged through said orifice and into theatmosphere it will contrast with the atmos phere during da light andconstitute a visual-signal use 1 in the da light, and

means for synchronously actuatlng the audible signal and jetting thevisual -signal means into the atmosphere; the soundings of the audiblesignal and the jettings of the visual-signal means corresponding 1nduration, and the intervals between the soundings of the audible signaland the jettings of the visual-signal means also corresponding induration.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
